📋Overview
Overactive bladder (OAB) is a common condition characterized by a sudden, uncontrollable urge to urinate, often accompanied by increased frequency and nocturia. It is a symptom syndrome rather than a disease itself and is typically caused by involuntary contractions of the bladder muscle (detrusor overactivity). The term 'overactive bladder' is the modern preferred terminology and is distinct from urinary incontinence, although they can coexist.
